+services send read receipts in all cases. This can very easily lead to a lot of wasted disk space in some

 There is also the case that each notitification rule will take some amount of CPU time to process, which
 is entirely wasted if the account doesn't check notifications.
 
 Ultimately for these reasons, we should allow bots and appservices to opt-out of server-side notifications
 upon registration.
 
-In all but the 0.01% of cases, appservice users generally don't need to receive notifications at all, so we could save everyone some computational cost by disabling server-default notification rules by default if the user was registered with a `type` of `m.login.application_service`.

 ## Proposal
 
-A new field `enable_predefined_push_rules` will be introduced to [`GET /_matrix/client/v3/register`](https://spec.matrix.org/v1.4/client-server-api/#post_matrixclientv3register)
+A new body field `enable_predefined_push_rules` will be introduced to [`GET /_matrix/client/v3/register`](https://spec.matrix.org/v1.4/client-server-api/#post_matrixclientv3register),
 which will allow users to opt-out of default notifications.

 When the `type` of registration is `m.login.application_service`, the default value of `enable_predefined_push_rules`
 will be `false`.
